MEDICINE-ADMINISTEEING INSTRUMENT EOE HOGS.

Specification of Letters Patent. Patent d M 17 192 Application filed July 3, 1920. Serial No. 393,964.

To all whomit may concern:

Be it known that I, RICHARD 1. SMITH, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in a Medicine-Administering Instrument for Hogs, of which the following is a specification.

This invention has for its objects to provide an instrument which may be readily inserted in the mouth of swine, will hold the mouth open, will not obstruct the mouth to prevent administering medicine, andto be of such construction that when applied to one of the jaws of a hog, it will not become detached, except by act of the operator. Other objects in view include the provision of an instrument which will be convenient in use and will consist of few and simple I parts so that it may be economically manufactured.

With the foregoing objects in view the invention presents a novel construction, combination and arrangement of parts as described herein and claimed, and as illustrated in the accompanying drawing, wherelFigures 1 and 2, respectively, are side and plan views of the instrument. Flg, 3 1s a sectional view between lines 33 of Fig. 1. Fig. 4 is a perspective view showing use of the device.

The invention consists, in part, of a bearing-strip 5, curved to form semi-circular end-portions 64 disposed opposite to each other in the plane of said strip, each endportion a being provided with a terminal loop 6, a'handle-member 6, approximately of l.-shape, being provided having its inner end provided with a prong c and secured to one of the loops 6, said prong and L-shaped handle-member 6 being disposed in the plane of the bearing-strip 5, whereby the parts mentioned will not be obtrusive when inserting the device in the mouth of a hog. the swinging movements of these parts being under manual control of an operator, and the mounting of the handle-member 6 being at the junction of the prong 0 and loop 6.

The remaining part of the instrument consists of a gripping-bar 7 approximately of L-shape, a prong 6 being provided and disposed in the plane of said bar, midway between the ends thereof.

It will be seen that by use of the handresult being that the mouth will be held in i open position; the operator also presses the hand-holds toward each other to cause the prongs to engage the opposite sides of the upper aw, as shown in the drawing, and while the mouth is thus held open, medicine either in liquid form or capsules may be administered. The prongs 0 and e, preferably, are of curved form and are disposed inclinedly toward each other.

The instrument as described is of great advantage since hogs may be securely and conveniently held for the purpose mentioned, and since it consists of few parts it will .be durable and may be manufactured at a very limited expense.

It will be noted that, on account of the described construction, the mouth of the hog will be practically unobstructed by the instrument while medicine is administered; and it is obvious that, as a feature of construction, the distance between the bearingstrip 5 and loops 6 may be increased, if desired, for maintaining the jaws farther apart, the movement of member 5 being in an arc the center of which is that part of the handle-member 6 which is parallel with member a. While the curved end-portions a could probably be dispensed with, they are of advantage since they tend to prevent injury to the mouth.

I claim: I

1. In an instrument for the purpose described, a bearing-strip curved to form approximately semi-circular end-portions dis posed in its own plane, each of said endportions being provided with a loop, a handle-member approximately of L-shape having one of its ends provided with a prong, said handle-member being secured to one of said loops and being disposed approximately in the plane of its prong and said bearing-strip, and a gripping-bar approximately of L-shape having a prong disposed in its own plane and projecting outwardly from its side midway between its ends, said bar being adapted to have slidable movements within with its prong disposed between the loops of the bearing-strip for in creasing or decreasing the distance between said prongs.

2. In an instrument for the purpose described, a bearing-strip having transversely disposed end-portions provided with loops, a handle-member approximately of L-shape having one of its ends provided with a curved prong, said handle-member being secured to one of said loops and being disposed in the plane of its prong and said bearing-strip, and a gripping-bar approximately of L-shape having a curved prong, said bar and its prong being adapted to be disposed in the plane of the handle-member and the prong thereof and to have slidable movements in the loops of the bearing-strip for increasing or decreasing the distance between said prongs.

In testimony whereof, I have affixed my signature in presence of two witnesses.

RICHARD I. SMITH.
